Recap.
Custom Hooks lets you share logic between components.
Custom Hooks must be named starting with use followed by a capital letter.
Custom Hooks only share stateful logic, not the state itself.
You can pass reactive values from one Hook to another, and they stay up-to-date.
All Hooks re-run every time your component re-renders.
The code of your custom Hooks should be pure, like your component’s code.
Wrap event handlers received by custom Hooks into Effect Events.
Don’t create custom Hooks like useMount. Keep their purpose specific.
